Answer:
2 inches per hour
Step-by-step explanation:
To convert to unit rate you can turn these 2 numbers into a fraction,
( the top part of the fraction is the inches unit and the bottom part is the hours)
16 and 8 into 16/8 then you simplify the fraction. So 16/8=2.
2 also equals 2/1 so its 2 inches every 1 hour.
